7 CAWa Objectives Overall Goal Contribute to Prevent Water Conflicts in Central Asia Objectives 1. Scientific and Technical Basis for Transboundary Water Management 2. Reliable Regional Data Basis and Regional Information System 3. Strengthen Interstate Communication and Cooperation 4. Capacity Building

8 Main Topics Data, Analyses, Systems Scientific Network Capacity Building Transboundary hydromet. monitoring network Remote sensing based monitoring Regional information system Regional climate change model Hydrological models Irrigation efficiency Groundwater circulation Research institutions all over Central Asia Data and knowledge exchange Cooperation in field research and modeling Joint publications and project proposals Training courses - on-site and elearning Exchange of scientists and technicians Summer schools and workshops

18 Selected Activities Regional Climate Model

19 Climate Change in Central Asia I Change in summer temperature Period A2 Scenario

20 Climate Change in Central Asia II Relative changes in precipitation for the period , relative to

21 Regional Climate Model REMO Scale Boundary and initial values Global Circulation Model Regional climate model REMO ~200 km Circulation patterns Statistical downscaling ~18 km Observation data Any other Source: DWD Source: adapted from PIK

22 Regional Climate Model Area REMO , A1B and A2 scenarios, 3 ensemble members

23 Postprocessing of REMO Data meteorological station (local)? hydrological model MOS & Weather Generator? distribution of daily rainfall REMO grid box (18km x 18km) REMO original station data REMO postprocessed

24 Selected Activities Hydrological Model

25 Climate and Hydrologic Models Regional Climate Model REMO Hydrological Model WASA Scenarios of water availability up to 2100

26 Hydrological Model WASA Climate forcing River basin water balance Model output: Time series of water availability variables Processes represented in WASA: Infiltration Soil water movement Evapotranspiration Runoff generation Runoff routing in river network Retention in reservoirs Model extension in CAWA project: Snow melt Glacier mass balances

27 Hydrological Model WASA Examples of required parameters Topography: Slope gradient Slope length River cross sections from Digital Elevation Models hillslope with terrain components Soil profile stream net twork TC 1 TC 2 TC 3
